Bug 138215 – The Page's muted setting should not affect the HTMLMediaElement's 'muted' IDL attribute

• Status: RESOLVED
• Resolution: FIXED
• Component: Media

[Ada Chan]

For example, if the HTMLMediaElement's muted attribute has not been set, but the Page's muted setting is set to true, querying the element's muted property in script should still return false.  The Page's muted setting is more of an override, similar to how the Page's media volume works.

Minor nit: "muted()" is cheaper than "document().page() && document().page()->isMuted()" so it should be first.

Nit: I think "page" should be in the method name. "setPageMuted" maybe?

Fixed.

Renamed as you suggested.

Thanks Eric!

Looks like this may have broken the windows build. Probably just a symbol export issue:

And as Joe noted, that broke Windows.  First attempt to fix it is:
http://trac.webkit.org/changeset/175393

The Windows 32-bit build error should be fixed with http://trac.webkit.org/changeset/175393.  Roger is going to help me figure out the symbol to export for 64-bit.
